Mercury Mariner Problems

Check Engine Light Illumination

The check engine light may come on due to failure of the Variable Camshaft Timing (VCT) solenoids. The VCT solenoids will need to be replaced if they are the reason the check engine light came on.

Knock/Pop Noise from the Steering Column when Turning

Looseness in the steering shaft and steering shaft coupling U-joint can cause a knocking / popping noise from the steering column when turning. The steering shaft and coupling U-joint will need to be replaced.

Transmission Oil Leaks from Left Side Half Shaft Area

If the transmission oil leaks out of left side half shaft area, it may be from a worn axle shaft seal. The seal can be damaged by a poor surface finish on the axle shaft. The axle shaft and seal should be replaced to correct the problem.

Mercury Mariner Recalls

Shift Lever Disengages From Transmission

For a vehicle that has had a remanufactured Ford automatic transmission installed, the shift lever bolt may be loose, allowing disengagement of the shift lever from the transmission. Dealers will inspect the transmission and either tighten the shift lever bolt or replace the shift lever assembly free of charge to resolve the concern.

Hybrid System May Overheat And Cause Stalling

The coolant pump for the hybrid system may fail, resulting in the hybrid system shutting down, and the vehicle losing power. Dealers will inspect and replace the original motor electronics coolant pump free of charge to correct the concern.

Power Steering Assist Loss

Due to a software issue that affects operation of the torque sensor, the electric power steering may stop functioning. This would make it difficult to steer the vehicle. Dealers will reprogram the power steering control module and instrument cluster module free of charge to resolve the concern. Dealers will also replace affected electric steering components as necessary upon inspection free of charge.

Mercury Mariner Reviews

I bought my Mariner in 2011 with 83k miles its a good vehicle with best quality ever. My last car was a 1995 Toyota Camry that I've purchased new but sadly totaled my vehicle an very reliable car ever too but needed another dependable ride. Overall love my Mariner its nice runs and drives like a champ, there no issues with nothing good car has good handling with the V6 and the performance is be...
Had the mariner for 7 months now and I am really pleased with it. The V6 has plenty of pep for me and I really like the 30+ miles per gallon. I like the visibility and the head room. Tried a chevy equanaux and could not get in without bumping my head. I had a 03 mariner and it was about the same but not as good gas mileage. I think I will stick with mariners.
2008 Mercury Mariner - I have had my car for 6 years, over 108,000 miles and have never had a single problem with it. It still rides great. I have never had to have the breaks replaced, not even the battery. Nothing leaks and the Sewell Ford dealership in Odessa, TX has the best service of any dealership I have ever used. They are the very best.
